The R-2000 Standard


The R-2000 Standard includes requirements related to energy efficiency, indoor air tightness quality and the use of environmentally responsible products and materials. It does not, however, specify exactly how a house must be built.

Rather, the R-2000 Standard sets criteria for how an R-2000 home must perform. This leaves the designer and builder free to choose the most effective, innovative and economical way to build it.


The R-2000 Standard is supported by an extensive program of research, development and testing.

The Standard is reviewed on a regular basis by Natural Resources team of technical experts and industry technical experts and industry technical experts. Before changes to the R-2000 Standard are adopted, thorough testing is carried out. Once the Standard is changed, home builders and other industry professionals receive training updates.


The R-2000 Standard sets out a series of house performance requirements that are in addition to those required by building codes.

In general terms, the R-2000 Standard involves the following:

Builder’s licence: Only home builders who have completed R-2000 builder training and hold a current R-2000 builder licence can build homes that can be certified to the R-2000 Standard.

Energy budget: R-2000 homes must operate within a specific energy budget, based on the characteristics of the home and the climate conditions where it’s built. Typically, R-2000 homes need 30 percent less energy to operate than conventional new homes. Common in R-2000 homes have high-efficiency heating ventilation systems, additional insulation, and an airtight building envelope.

Whole-house ventilation: Every R-2000 home must have a whole-house ventilation system that supplies ou8tdoor air to all living areas in the home. This system must be designed and tested to meet the CSA International Standard CAN/CSA-F326 M91 (“Residential Mechanical Ventilation Systems”). Installers must be trained by the Heating, Refrigeration and Air Conditioning Institute of Canada or equivalent.

Environmental pick list: Every R-2000 home builder must choose from a “pick list” of options for indoor air tightness construction and environmental features. The indoor-air-quality features can include items such as hardwood flooring, low-emission cabinetry, low-emission (low volatile organic compound [VOC]) paints, and non-solvent-based adhesives and finishes. Features to conserve materials include choices for insulation, siding, sheathing, wall studs and foundation drainage.

Safer heating: The heating systems in the home must not be susceptible to combustion spillage.

Water conservation: Every R-2000 home must be equipped with water-conserving toilets, faucets and shower heads.

Independent inspections: Every home submitted for R-2000 certification must undergo a series of independent inspections and tests to verify that the requirements of the R-2000 Standard have been met.
